There's three ways to do dots that I know of. One, is to get some pre-cut, .050" thick dots and drill holes to the exact depth needed, or shim/fill them to the proper depth after drilling; two, get some sort of rod (plastic, wood, metal), drill the holes, cut pieces of rod slightly longer than each hole, glue them, then file them flat - stainless would be hardest, but not impossible. Three, use some sort of epoxy/resin/paint to fill the holes with a liquid that hardens. I'm leaning toward option three, just cause I don't have any way to regulate drilling depth
that precisely.
It's going to be harder to get really consistently-placed holes than it will be to fill them, I think. If a pickup is a few thousandths of an inch crooked you'd never see it, but I'll be staring at those dots every day...

I just finished the poly on the neck last night, cause I'm not about to wait for six weeks to even get started while I agonize over stupid little dots. I can always re-seal the tops with something. I have one friend, a studio player in L.A. who tells me that fretless basses should
all have fret lines as well as dots, and another friend who owns a studio in Minneapolis and has played on hundreds of projects who says
any markers would be wimpy and I should play by ear. :toothy12: Surely I'll give that a try first, but almost as surely, I'll end up going dotty. :binkybaby:
